Brake of motorcycle
Technical field
It the utility model is related to a kind of motorcycle disc-brake.
Background technology
It is high when disc brake forms brakes by the braking clamp of a brake disk being connected with wheel and disk border
Pressure brake fluid promotes brake block to be allowed to clamp brake disc so as to produce braking effect.
Disk type brake is also in disc brake sometimes, and it is divided to ordinary disc-type brake and ventilated disc to brake two kinds.Ventilated disc
Brake is that many circular vents are drilled out in card, or cuts out ventilation slot on the end face of disk or precast the ventilation of rectangle
Hole ventilated discs brake is more preferable than ordinary disc-type brake using distinguished and admirable its cold and hot effect of effect.The major advantage of disc brake
It is that can be braked rapidly when high speed is braked, radiating effect is better than drum brakes, and the constancy of brake efficiency is good, is easily installed picture
Advanced electronic device as ABS does not have to drum using metal derby (dish), there is a flat brake on the both sides of brake disc
Hoof, the oil pressure when master cylinder are sent to a point cylinder, brake shoe is clamped to brake disc, to reach tight effect of stopping, nowadays
Front-wheel is commonly used to, the advanced car device four-wheel disc brake having, its advantage is that effect is sensitive, and radiating is good, it is not necessary to which adjustment is stopped
Workshop gap, maintenance are easy.
The operation principle of disc brake brake system is that the disc of one piece and wheel synchronous rotary is installed on flower-drum, and in front fork
With device clamp on vehicle frame, then through the brake shoes in clamp disc is clamped, reach the purpose of brake, such disc brake system mistake
Go successfully to use for many years on locomotive, and as the main flow of locomotive brake system.
Distinguished according to the mode of braking action, or say and divided with the medium of start brake block clamping disc, when brake cable, one
It is oil.
Mechanical disc brake, rubbed by the pulling force of brake cable by the brake block in clamp and clamp disc, produce braking effect.
Hydraulic type, using fluid as medium, drawing brake, pressure leads directly to clamp from oil pipe being that piston inside start compresses fluid, so as to
The piston in clamp is promoted, drives brake block clamping disc.Mechanical disc brake has the convenience in its compatibility.The brake of hydraulic disc brake
Handlebar, oil pipe and clamp are the set products completely coordinated, natural and conventional cable start the no common common factor of brake.
Existing disc brake exist one it is bigger the problem of, be exactly that braking effect is unstable.Main cause is that brake disc is straight
Connect in outdoor environment, amount of dust or sandstone airborne dust in outdoor environment on temperature, humidity and road surface etc.
The braking effect of brake and unstable will be made.Especially northerly winter, between one side technology brake disc and caliper
Coefficient of friction can decline, braking effect is excessively poor.If encountering sleety weather, thin ice can be freezed on brake disc, this has very much can
It can allow motorcycle brake failure, cause serious traffic accident.
In addition, can typically set ash discharge groove and heat emission hole on brake disc, under normal circumstances, ash discharge groove can allow caliper with
Abrasive dust is thrown away from ash discharge groove between brake disc, and heat emission hole can increase area of dissipation, is radiated from brake disc through acceleration.But
On silt road, substantial amounts of soil can be adhered on brake disc, on the one hand can reduce braking effect, it is on the other hand, hard in soil
Matter particle can allow caliper or brake disc Fast Wearing, reduce disc brake service life.In addition, silt can block ash discharge groove and radiating
Hole, chip can not be discharged radiating rate reduction.
The content of the invention
The purpose of this utility model is to provide a kind of brake of motorcycle that can ensure that disc brake braking effect is stable.
To achieve these goals, this practicality includes brake assemblies and wheel hub, and brake assemblies include caliper, brake disc,
Brake disc is fixedly connected with wheel hub, it is characterised in that
Protecgulum is fixed towards the side of wheel hub in brake disc on wheel hub, protecgulum is towards a side opening of brake disc, and opening is directly
Footpath is more than the diameter of brake disc, and brake disc is fixedly connected with wheel hub;
The brake assemblies include a bonnet, and rear cover gab is relative and coaxial with preceding cover gab, between protecgulum and bonnet
It is slidably matched, surrounds sealing space;
The caliper is located in bonnet;
The end face lower end of the bonnet sets air admission hole, and the bonnet sets dividing plate, dividing plate between end face and brake disc
Excircle be connected with bonnet inner wall sealing, between dividing plate and the bonnet end face face of cylinder bottom set exhaust water hole, institute
Setting passage at the center of dividing plate is stated, screen pack is set between the air admission hole and passage, and air admission hole lengthwise position is less than
Passage.
By setting protecgulum and bonnet, brake disc is surrounded, can ensure brake disc not by rainwater, the shadow of silt
Ring, make braking effect more stable.
Covered after and set air admission hole and exhaust water hole can be to the cooling of progress Fast Persistence in braked space.
Further, airscoop shroud is set outside the air admission hole, drives gas port on airscoop shroud into, inlet charge direction with it is rear
Cover adjustable on parallel face.The adjustable airscoop shroud of airintake direction is set, air inflow can be adjusted, can also prevent the entrance of water, is fitted
Different weather and season, such as rainy day are answered, can be by the air inlet mouth down of airscoop shroud, summer can be by mouth towards direct of travel.
Further, the exhaust water hole is externally provided with drainage hood, and drainage hood longitudinal section is arc, its both ends open, is open
Direction is parallel with motorcycle length direction.The effect of drainage hood is that the exit level for making air quickly from exhaust water hole flows through,
Negative pressure is formed in exit, aspirates the water and air inside drum brake, accelerates draining, and cross-ventilation, ensures cooling-down effect and row
Water effect.
Preferably, the screen pack is horizontally disposed with, and is fixed between dividing plate and bonnet inwall, by dividing plate and bonnet inwall it
Between cavity be separated into two parts up and down, the lengthwise position of screen pack is less than passage.
Further, prolong even circumferential on the brake disc friction operation surface and be provided with a plurality of chip area;Stop on chip area edge
Hull body rotation direction is obliquely installed, and the chip area is inner and brake disc friction operation interior surface edge is provided with gap,
Chip area outer end is on brake disc friction operation surface external edge;Diameter where the chip area is inner and chip area have
One or seven ten degree of angles;Two groups of radiating pore chains, the heat emission hole of one group of radiating pore chain are equipped between two adjacent chip areas
Number is four, and the radiating hole number of another group of radiating pore chain is five;The radiating pore chain inclines along brake disc rotation direction
Tiltedly set, the angle of inclination for the pore chain that radiates and the angle of inclination of chip area are engaged.Brake disc friction operation prolongs circumference on surface
A plurality of chip area is uniformly provided with, and chip area prolongs brake disc body rotation direction and is obliquely installed, and can will effectively be stained with brake disc master
Impurity on body excludes from chip area, avoids braking disc main body and brake caliper is worn.Thinner thickness at chip area, adds
The fast radiating rate of braking disc main body.Multigroup radiating pore chain is uniformly provided with braking disc main body, radiating pore chain and chip area have
Rule and it is evenly provided on brake disc friction operation surface, effectively helps to brake disc main body and equably radiate, avoid portion
Divide deformation and damage braking disc main body.
